lame newbie product intallation q's...
by Ken Gunderson 17 May '04

17 May '04

Greets Folks: I have really basic question- I want to run a couple different Zope/Plone sites. My assessment is that multiple zope instances offer a better fit for my needs than VHM. Some products will be shared between sites, and others not. My question is where to best install these products and why? Plone docs say INSTANCE_HOME. Seems rather redundant to install multiple copies, so can just maintain one plone product dir somewhere and symlink as needed. Else another possibility is to just put into top level /usr/local/www/Zope/Products dir and let all instances inherit. Or is there some downside to this?? Enlightenment appreciated. Thanks bunches. -- Best regards, Ken Gunderson GPG Key-- 9F5179FD "Freedom begins between the ears." -- Edward Abbey

DTML Method - delete files
by Laura McCord 17 May '04

17 May '04

I am almost done writing the script but I need to figure out how to compare two dates. For instance, I have this: <dtml-var ZopeTime fmt="%m/%d/%Y"> <dtml-var modification_date fmt="%m/%d/%Y"> *** Now I need to compare the two dates to see if the ZopeTime is greater by 5 days. Any ideas on how to do that using dtml?

zope management problems
by sandor marton 17 May '04

17 May '04

Hi there, I'm new to Zope and Phyton. My problem is that when i try to access on the Plone Controller the Zope management interface after i entered the username password pair it doesn't accept it and after 3 tries it says that "You are not authorized to access this resource." I used the Phytonwin Editor interface to generate the inituser file entering the username and password but leaving anything else as default. The installation of Plone otherwise whent OK. Typing localhost:80 I get the Plone page, typing localhost:8080 i get the Zope Quick Start page, but i have this problem with the management stuff. I installed Plone an Windows XP and I use Internet Explorer version 6. The inituser file looks like this...: a:{SHA}hvfkN/qlp/zhXR3cuerq6jd2Z7g= Any help it's greatly apreciated!

storing files on Apache and authenticating
by Laura McCord 17 May '04

17 May '04

I have accomplished a lot thanks to several of you pointing me in the right direction. I am using PloneExternalFile and when files are uploaded by a user they are stored in the /var/www/html directory to be accessed through the Apache server. I have a cron job that executes a python script that will delete any Plone External Files that are older than 5 days. The next thing to do is somehow perform a user authentication when accessing files through the Apache server. Clients are going to access a file that is stored on the Apache server by an employee. The Client needs to enter their password/username to access their files. How would this be done if there are going to be several clients and they cannot have access to each others files? The problem that I am thinking about is that I would need to know the directory ahead of time that the employee is going to use to put the files in. I am certain there are also other issues that I have not concerned such as how to create the username/passwords. Either have the employee create them through the form to which they upload the files or already predetermine what their password is going to be and place it directly in a .htaccess file. Any suggestions? Thank You, Laura

RE: Leaking HTTP requests (was: RE: [Zope] Leaking Acquisition.Im plic itAcquirerWrapper)
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 17 May '04

17 May '04

G'Day, OK, so I've tried to flush the cache, and look at the ref counts, and nothing jumped out at me other than the usual suspects. I often see refcounts to a variety of my own content types/classes, but they seem pretty stable. Since they represent a large portion of our content, I'm not worrying too much about them, though I probably should and soon will. Here's an interesting technique I'm using: First, in ZPublisher I patch HTTPRequest.__init__ to maintain a global list of weakref's to the instances created. This gives me a way to access existing HTTPRequest instances, notably the ones that are sticking around that shouldn't be. I'm also adding a unique id (In the form of a counter) to each request so I can uniquely identify them. Then, I write an external method and use the gc module to find out the referrers/referants. I'm hoping this will give me some clues as to what's holding the requests around. Right now I've managed to use gc.get_referants() with great success. I can dump (using pprint) the request object and read it's contents. Once I've got a few samples taken, I'll hopefully be able to track down whihc ones are actual leaked requests (by their id), and see if they have anything in common. I tried briefly gc.get_referrers() but I get ugly errors. Another idea I had was to through the frame stack upon __del__ of a req and log that info to see if there's a commonality to those also. One question: is this bad when applied to a persistent object?: setattr(self,'thumbnail', Image(id='thumbnail') ) (I've monkey patched CMFImage to have thumbnails) Thanks and cheers, J.F. -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: May 16, 2004 5:48 PM To: Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca Cc: stefan(a)epy.co.at; zope(a)zope.org Subject: RE: Leaking HTTP requests (was: RE: [Zope] Leaking Acquisition.Im plic itAcquirerWrapper) Jean-Francois.Doyon(a)CCRS.NRCan.gc.ca wrote at 2004-5-14 17:23 -0400: > ... >I'll leave the iste running throught the week-end and we'll see what shows >up. >"high" refcounts is somewhat arbitrary I guess ... When you say high you >mean >high and stable or high and growing? In fact, I mean unexpectedly high. The relevant references counts are not necessarily the highest ones. For example, when you make catalog searches, it is completely normal that you see lots of "DateTime" objects. Nevertheless, you can be sure that they are not the cause of memory leaks. The same applies for acquisition wrappers. You must look for usually rare objects that suddenly show up in large numbers. It may help very much to clear the ZODB cache ("Control_Panel" --> "Database management" --> <databases> --> "Flush Cache" --> "Minimize"). This should delete all objects from memory that are "normal" artefacts of Zope processing. Apart from a few objects only the leaked ones should remain. Be warned, there was a bug in "cPickleCache.c" that led "Minimize" enter an infinite loop. I am not sure whether this bug is fixed in the current Zope 2.7 release. >Right now, the only suspect class as far as refcounts (Other than the HTTP >requests) is the DateTime one.

Is the site "frontended" by Apache or Squid or IIS or something else? Is there anything in those logs? - C
